The PCM (powertrain control module) is located behind the glove box. If removing you need to disconnect the negative cable for the battery first. You have to remove the glove box to get to the retaining strap bolts on the inside and you have to remove the cabin air filter and box to get to the three main cable connectors in the engine bay. To remove the cabin air filter box you have to remove the windshield wipers and cowling plastic and the firwall cross brace.
